I can't connect to the Internet on Windows

I have installed Boot Camp and Windows XP onto my iMac Intel and I can't connect to the net with Windows. I have done a search for this problem and have found out that the Macintosh Drivers disk did't install properly. I tried re-installing the drivers but a box came up with "This software does not support your hardware - The wizard was interrupted before macintosh drivers for window xp could be completely installed"
